Leaking Sink - Poor Workmanship Or Due To Cheap Sink?

[kueh 0]

Hello,

I keep having leaking kitchen sink problem. Kitchen sink is mounted underneath the solid top. Have tried to scrap off silicon; refill with silicon. The problem will come back after a few months.

Is this due to poor workmanship as in the contractor did not do the job properly or a cheap sink is being used? Expansion or contraction of the sink?

What should I do to resolve this painful repetitve issue? Change the sink? Possible to use existing back solid top?

Anyone has similiar issue?

Thanks.

When you did your sink reno?

If within 1 yrs, possible is the contractor didn't do a property job.

For undermount sink, they need to add sth or do a process to prevent leaking.

Call your contractor, ask them to correct it.

Silicon is hopeless. Try something better. I recommend Shelleys Blockade. Is very sticky and much more durable. Cost $10.xx at Homefix.

some sinks have thinner sheetmetal, so warps easily.

But normally for undermount, if u got put generous solid surface overhang like 10mm, then seldom leak.

i would suggest to find the source of leak.

It could be the tap or the waster water trap.
